Effects of perioperative hypothermia on patients’ vital signs during TURP / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the effects of unwarmed and warmed irrigation fluid on patients’ vital signs during transurethral resection of the prostate (TURP),and to investigate the related factors affecting the safety of TURP. Methods A total of 100 patients were randomly assigned to receive unwarmed (21℃,n=40)or warmed (37 ℃,n=60)irrigation fluid during TURP.Pre-operatively,their age,body weight,IPSS,ratios of heart, brain, lung complications,intra-operative anesthesia modes,irrigation time, irrigation fluid amount,resected prostate weight and blood transfusion amount were not significantly different between the 2 groups. Intra-operatively,their mean arterial pressure (MAP),heart rate(HR),body temperature(T),blood oxygen saturation (SaO 2) and osmotic pressure of plasma (Osm) were observed dynamically based on the operating time. Results In patients of unwarmed group,after 45 min in the process of TURP,on an average MAP was decreased by 7.6 mm Hg (1 mm Hg=0.133 kPa;F=1.334,P=0.262);HR was reduced by 21.6/min (P
